UNITED STATES A PATENT OFFICE.

INK-DISTRIBUTER FOR, PRINTING-PRESSES.

Application filed February 12, 1921.

To all 'whom t may concern.'

Be it known that I, Eo'ros F. MARCEAU, a citizen of the United States, residing at East Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Ink-Distributers for Printing-Presses, of which the following is a specification.

This invention relates to those appliances which are adapted to be applied to printing presses for keeping the roll in the ink founsupplied with the desired quantity of The object of the invention `is toprovide a simple and cheap appliance which can be readily attachedy to common forms of printing presses and which has means that will automatically travel back and forth and uniformly distribute thick ink in the required uantity to the desired area on the roll in t e ink fountain when the press is running.

In the accompanying drawings Figure l shows a plan of an ink distributing appliance which embodies the invention. Fig. 2 shows a transverse section on the plane indicated by the dotted line 2--2 on Fig. 1. Fig. 3 on larger scale shows a plan of one end of the appliance with partsy cut in section. on the plane indicated by the dotted line 3-3 on Fig. 2.

The appliance illustrated comprises a pair of brackets 1 which are designed to be fastened to the upper edges of the end walls 2 of the ink fountain 3 which is of common shape. The brackets support a rotatory shaft 4 provided with two reversely out spiral grooves 5 between the brackets and a drivmg pulley 6 at one end. Two rodsl connect and tie the brackets together and movable on and guided by these rods is a yoke 8. A crescent-shaped block Y 9 is arranged to project into the shaft grooves. This block "has a stem 10 which loosely fits a hole in the middle of the yoke. Projecting from the stem of the block is a curved linger 11. Adjustably secured to the yoke and projecting into the fountain adjacent to the surface of the'ink roll 12 is a distributing arm 13. On one of the rods 7, and adjustable along itVare two collars 14, which have Specification of Letters Patent.

stop' pins 15 that project parallel with the axis of the shaft into the path of the finger 11 on the crescent carried by the yoke. The collars are fastened in position, after being adjusted, byset screws 16. The ink roll shaft 17 is supported by the end walls of the fountain and has a gear 18 that is designed to be engaged with the usual gearing of the press.

When the press to which the appliance is attached is run the rotation of the grooved shaft feeds the crescent-block and this causes the yoke totravel along the rods and carry the distributing arm in the ink fountain along the face of the roll. When during the travel of the crescent the linger engages a stop pin, the crescent is turned so as to be engaged by the walls of the reverse groove in the shaft, and consequently is then fed in the opposite direction. This carries the yoke and distributing arm back until the finger engages the other stop pin and the crescent is again turned. By this means the distributing arm 'is caused to continue to travel back and forth and keeps the ink up against the surface of the roll. with the stop pins may be secured to the rod in any required positions so that the ink. will be applied to the roll at only the desired section, and the distributing arm is set so that the proper quantity of ink will be spread along the section of the roll to be inked. 4

The invention claimed is:

An ink distributer, comprising brackets, rods connecting the brackets, a shaft provided with reverse spiral grooves supported by the brackets, means for rotating the shaft. al yoke movably supported by the rods, a distributing arm projecting from the yoke, a block swiveled to the yoke, and eX- tending into the grooves in the shaft, a finger extending from' said block, collars ad justably secured toone of said rods, and stop pins projecting from the collars and adapted to engage said linger and turn the block for reversing the travel of the yoke and distributing arm.

The collars
